IMPROVEMENT |N STEAM-TRAPS.

Specification forming part of Letters Patent No. 196,764, dated November6, 1877 application filed June 30, 1877.

To all whom it may concern:

Be it known that I, CHAS. F. PIKE, .of Phil- Fig. 2 is a modification ofthe small curved bar d.

a is a tube. 1) b are supports. a 0, Figs. 1 and 2, are curved bars. dis a small curved bar. 0 0, Figs. 1 and 2, are connecting-pieces. f is arod to communicate motion to a valve on the lower end of the tube a. h,Fig. 2, is the same asf, Fig. 1.

The supports 1) b are secured upon the ends of the tube a. The curvedbars 0 c are fastened to the supports b b. Then, by means of theconnecting-pieces e e, the small curved bar d is held firmly in place.On the lower end of the tube a is placed a valve of any desiredconstruct-ion. The steam enters the tube a at 4 its upper end, heatingand expanding the tube. This carries the ends of the bars 0 c from eachother, causing the centers of the bars to move toward the tube a. Thismovement of the centers of the bars 0 0 brings the ends of the smallcurved bar 61 nearer together, causing it to move the rodf. The rodf,being-connected to a valve on the end of the tube a, its motion closesit. When the water caused by condensation fills the tube a it cools andcontracts.

it, reversing the operation above described, opening the valve, allowingthe water to escape. This operation is repeated automatically.

The bar d can be fastened to the bars 0 c in various ways.

The small curved bar 01, instead of being made in one piece and sprungin its center by the motion of the curved bars 0 0, can be constructedasshown in Fig. 2 at g g.

What I claim is The combination of the tube at, having longitudinalbars'c 0 attached thereto, and curved bar (I, provided with a rod forcommunicating motion to a valve, as and for the purpose specified.
